Dipole Antenna - GWX

[Timber.Wolf]

I've played GWX extensivly when it first came out and then had to take a longer break. Just a few hours ago I reinstalled the game+patch+ sh3 commander. After starting a new game in the year 1939 with the second flotilla I have noticed an antenna slowly turning on my bridge. It wasn't there before, why is it there now?

I guess it's a feature that was implemented since 1.0?

Welcome:up: Timber.Wolf

It is a new feature, I think it came in 1.02, somebody can give you the scoop on what exactly it does.

Good hunting:yep:

Sounds like you are referring to the RDF loops.

We fixed 'em.

Here's your potato peeler. Fritz is looking for you in the galley.

Onions today.:D

What doe's it do ?:hmm:

[Kpt. Lehmann]

(LOL can't resist.)

It rotates!:arrgh!:

[FIREWALL]

Thx Kapt.

I had that comeing. :D :rotfl:


Played GWX last nite :rock: :rock: :rock:

SH-4 :hmm: closest i can come to YAWN :D

[Kpt. Lehmann]

Radio Direction Finder. It retracts when you submerge. You can consider it representative of a Radar Warning Receiver too... at least when the Biscay Cross isn't up.

This corrects an unfinished feature that was meant for stock SH3.

Welcome aboard kaleun Timber Wolf :arrgh!:
Enjoy the GWXperience matey :rock:

@Kpt....the old ones are still the best hehe ;)

Hello,
whether the turning dipole is a nice feature as far as i read it did not turn in reality. Hard to belíeve - has anyone evidence of this thing turning ?
Thanks and greetings,

It was turned manually, probably not as fast and as often as depicted. The loop was used in conjunction with the wire antenna running from the deck to the tower and back to the deck. The wire "caught" the radio transmission and the loop found the "null". Together they were used to find the bearing of the radio transmission.

You don't see anyone turning it inside, or outside, for a reason. To keep Bernard away from it so it works as it should ingame. He's not even trusted to lower it when the Uboat dives. :yep:

[Timber.Wolf]

Thanks for the warm welcome :D

Besides downgrading to decembers GWX there isn't really a way to get rid of that antenna, is there?

I love GWX and thought it was a real shame it wasn't even mentioned at the Mod Of The Year awards (seriously, GWX should at least have been mentioned), and it's great somebody took the time to implement a lost feature, kudos, but that antenna constantly distracts me. It might just be the fact that I'm a grumpy old guy, resistant to change, but I like things the way they used to be :p

[ref]

Just enable GWX - Lowered DF Antennas (included on the 1.03 patch) with JSGME.

Wonderful, but it came with 1.03? That means it should be listed in the Generic Mod Enabler after everything was installed, right?

I can't seem to find it, neither is it listed in JSGME nor is there a folder for it in the MODS folder.

Please don't tell me that I have to reinstall everything.

Please look under optional mods.

Ok, this may be off topic, but since we are on the topic of newbie questions, I have one I haven't figured out/can't remember.

If playing GWX, with Map Contacts off - will you ever get a RDF hit that shows you where a boat is nearby?

I play in very low time - and haven't ever seen it happen. The most I have gotten is radio reports from Bdu, but I can't ever remember having a contact show up in my vicinity - should I enable Map Contacts for that?

Thanks for any responses to the newb question.

Tchuss,

what controls the raising/lowering of the DF antenna? How is that coded? :hmm:

I know this is going to be a little pedantic, but it isn't a dipole, it's a loop.

The RDF loop on u-boats (and just about all other craft at that time) was for low frequency use, near 500 KHz. A characteristic of small shielded loops is that they have two very sharp nulls which are useful for finding the direction to a station. The only problem is that you will only get a line of bearing, ie., the target could be at 270 degrees or 90 degrees, because without a sense antenna to resolve the ambiguity, there is no way to tell which direction the signal is coming from.

The intended use of these antennas was to get bearings on known beacons in fixed locations. In that case, the ambiguity is resolved: If you are in the North Sea and you get a line of bearing like 135/315 degrees true for a station in Germany, then you know it has to be 135 degrees. The idea was that you could take bearings on two or more stations, and where the lines overlap on the map is your location.

They were also used by boats in wolfpacks to home in on a beaconing boat that was shadowing a convoy. Beaconing was used because various navigational errors by both boats could place the intercepting boat miles away, whereas with a beacon signal and an idea of the general direction to head, you can intercept easier. You can also take a bearing, run in a straight line at high speed for an hour or so, take another bearing, then you have two bearings, and a general idea of the location of the beaconing boat.

It is possible to make a dipole to receive these beacons, but a full sized dipole for 500 KHz would be just under 900 feet long, not very feasible, and in any case the null off of the ends of even the best dipole is nowhere near as sharp as the nulls on a shielded loop.

nice write up!
